Percival will ask E. K’lani

“So Polk hated any magical practice that was not using the runes, and forbid us from using them, such as alchemy and the witches magic. I know there are risks doing any form of magick, but what are you’re thoughts?”

"They aren't as predictable. Take it far enough and you loose yourself, go further and, you leave shards...speaking of, the Dallas House is, inhabited by one. But so are the woods.
Runes have a logic to them, even if it's a demonic logic. It's predictable."

“A witch? Or a shard… fragment?”

Eerling: "Does it matter? If it's still there, it's not the worst thing in that house. It's probably a daughter of Dimitree but daughter, shard, fragment, what it is exactly doesn't matter. It's dead and we're going to kill it if we have to. With a witch, what better place to hide something from Polkdot. If she's moved on, great, if the house is gone, we'll rebuild it. ... of course if she is there and we disturb her...she'll probably eat both or one of you two alive."
